ymorefwo'od or fibrous portions' therewithin tol receivethe railroadwspikes.

,c provide a tie offth'e" 'character' designated ywherein the tubular bodyis strongk andrigid construction that the Vrailroad rails maybe A readily but very securely fastened thereto and positively'held inposition 1longitudinally ,of

, l i further purposeisl toprovide' a tie of` this j-type' wherein one layer of they metal of y thev tubular bodyis providedz uponj theA top 2Grof thewooden core and beneath the railand anothery layer-on the top :of the", metal Ybody k*of the ,railb-ase so asto positively position 5 lthe ,tie 5' and, further 1 preferably to have onev Y yor ytwo of thesidesofu thefbo'dy adjoining the` l upper layer of the body passy immediately be-.V

low therail at fkthesides of the tieso yas to hold the upper ,or outerV layer of. thetwo ytop 1 ylayersiin place iirrnly against the'innerlayer andtso as to aid in distributing4 the' strain of weight and use over al large `part of the tie and onto a considerableportion of the vwooden or other core. y e.

invention will appearffromthe specification' and claims herein. f r ri' l Fig. l is an isometric view'of a composite A tie embodying my'nvention with oneri-anvil1 v 4o place thereon. 4 t y Fig. 2 s y-avertical longitudinal ysection through'a part 'of said tiefan'd one 'of the rails Fig. 3 is a transverse sectional View through the tie'and aside elevationfof the rail online y 3 3 of Fig. 1.` t

' titular description it willvbe seen that the.

compositel railroad tie here shown comprises a woo'denfor other( fibrous core 8 and a metallicv tubulary body 9 yplaced 4thereabout.y The y core 8 is nearly the heightand `width of the 55 complete tie and may be in the form of a short) ,e e t Y ,y v, y section underneath each rail 10 asshownin Affu ther purposefof. thefinvention is to" Fig.-2 or 'it may bethe ullylengthof'the tie or at least long enough ,soA thatfone suchI y p e l n t y `wooden or fibrous section reaches beneathv 60 i 'when assembled and particularly is 'of such,A A 1 l both of the rails 10. v y The metallic tubular body 9 is' preferably ,t yformed of sheet metal of the desired oharacf;

ter and thickness by `bending or otherwisejm *i @forming the sheet of metalffo'uror live times lb" so asv to form a substantially rectangular tube.. consisting ofthe bottomy 11 andopposite upa standing sides 12and 13 and two toplayers` 14 and 15. Said two top layers overlap close;j 0

' lywith the layer 14 being the inneronel and is provided to extend along the oppositeV edges 'the layer 111. The tube thus formed isof a the rail ragainst lengthwise ,movement upon thelayer'l the outer one, thaty ison top; of

sizeto admittherewithinthe core ortblockrx 8 of ywood orfother brous'materiah Gon-I veniently the said core is inserted yfromyeither and core when assembled fit eachfotherrela-ri tively closely both laterally andyertically.`

' In'allforms ofthe constructionijthe outer so* wise formed with railbase-receiving aper-jf tures' 16l at thepoints in the tieiwhere the y rail lOis to be located. Thisrailbase-'receive ing aperture extendslongitudinallyof the tie for the width of the railbase 10aL and ex#` tendsftransversely of the `rail orthe full!V width of the said outermost top layer 152C .This aperture allows Athe bottom of'the railbasellO to rest flat down upon the upper '90 surface of the inner toplayer rlllvofjthe'me-` talliobody and this innermost'layer 14 `in turn rests flat against the top of the wooden block or other tibrous core 8, whichyin turnV at itsv bottom rests upon the bottomtll of the metal body. f It will be seen that as far as theparts so far mentioned, this obtains a strongl direct distribution of the weightand i 10'r1 rest flat upon the innermost top layer 14 wear and cutting away of the tie by pressure from the rail is avoided. c

In allforms of myconstruction the cutting 'or forming ofthe rail-receiving aperture 16 leaves two oppositely spaced vertically extending edges 17 and .18Q'uponth6 outer layer 15 which edges form shoulders, to
